Point Blank Online Cubase Advanced

Curious if anybody has taken the Cubase advanced course from point blank online. I’ve been a cubase user since SX but am completely self-taught. It looks like this is a course that covers a broad spectrum with recording, production and mixing. I am mainly looking for ways to speed up my work flow and learn some things that i don’t already know. I know that it might be possible to learn everything on my own but it looks like a course like this could help a lot.
